SPLIT SPIDER FOR OIL-WELL GASINGS AND THE LIKE.

Application fii'ea April 2,

To all whom it may concern:

Be it known that we, JAMEs B. GooKn and CHARLES A. .WILSON, citizens of the United States, residing at Los Angeles and Torrance, in the county of Los Angeles and State of California, have invented new and useful Improvements in Split Spiders for Oilell Casings and the like, of .which the following is a specification.

Our invention relates to split spiders for oil well casings and the like, and consists of the novel features herein shown, described and claimed. a

An object is to make a spider in two pieces for use in carrying slips, in raising and lowering drill stems, flow pipes, pump tubing, and the like, and which may be readily separated and removed laterally from the stem'or cable passing through it.

Other objects and advantages will appear from the drawings and specification.

The drawings illustrate the invention.

Figure 1 is a perspective showing the top of one piece and the bottom of the otherv piece, the two pieces ready to go together to form a split spider, in accordance with the principles'of our invention.

Fig. 2 is a top plan view upon a reduced scale and showing the two pieces of the spider assembled and fastened together by bails and ready for use, parts being broken away and shown in section.

Fig. 3 is a side elevation looking in the direction indicated by the arrow 3 in Fig. 2.

Fig. 4 is aside elevation looking in the direction indicated by the arrow 4 in Fig. 2.

The details of the split spider shown in the drawings are as'follows.

The split spider comprises the lower part 1 and the upper part 2. The lower part 1 has a straight flat lower face 3 with a vertical opening 4 at one side of its vertical axis, the opening 4 being half round. A notch 5 is formed from one side of the lower part and extends to the vertical faces 6 and 7, said faces being in a longitudinal line diametrical of the completed opening. Flanges 8 and 9 extend upwardly in longitudinal alignment at opposite sides of the notch 5, there being supporting blocks having flat faces 10 and 11 parallel with the lower face 3 at corresponding sides of the flanges 8 and 9; A half bearing block 12 extends upwardly as claimed.

from the face 3 and connects the material forming the; faces 10 and 11, the opening 4 being formed in the inner side of the bearing block 12. Vertical pillars 13 and 14 extend outwardly from the ends of the bearing block 12 toward'the faces 10 and 11 and parallel with theflanges 8 and 9. The bearing block 12 is the full height of the assembled spider.

The upperv part 2 has a bearing block 15*fitting in the notch 5 and having a supporting blocks have faces 23 and 24, which are parallel'with the lower face 25 of the block 15, so that when the face 25 "is level and forms a part of the face 3,. the faces23 and 24 fit upon the faces 10 'andll.

The flanges Sand 9 fitting inthe recesses 19 and-20 and the pillars 18 and 14 fitting in the recesses 21 and 22 hold the bearing blocks 12 and 15 together, and when the parts 1 and 2 have been assembled bolts 26 and 27 are inserted through the ends of the bails 28 and 29 and through the blocks 17 and 18 above the faces 23 and 24 and through the flanges 8 and '9,

thereby securely connecting the parts 1 and 2 together to'form a spider for holding slips and to be operated in the usual way. When-a stem such as a drill stem or a cable is extending through the completed slip opening 30, formed by the half openings 4 and 16, the spider may be readily removed laterally by removing the bolts 26 and 27 and lifting the part 2 upwardly relative to the part 1.

Various changes may be made without departing from the spirit of our invention We claim:

1. A split spider having in combination ways therefrom, a complementary half.

bearing block having a half round opening, recesses adjacent theedge ot the block to engage the said pillars, and faces secured to the outer edge of the hall bearing block andadapted to contact with the flat faces first mentioned.

3. A split spider as claimed in claim 2 having flanges on the flat faces of the lower bearing block adapted to engage recesses on the flat faces of thecomplementary bearing block.

4. A split spider having in combination a lower part having a halt bearing block with a halt round portion, flat members extending from each side of the half bearing block and from one end thereof, flanges on said members, a complementary halt hearing block having a halt round portion, fiat members extending from opposite sides thereof and adapted to engage the flat members of the lower bearing block, and recesses therein adapted to engage the flanges on the lower bearing block.

5. A spider comprising two half bearing blocks, overlapping blocks extending from the bearing blocks and carrying inter-locking means to resist movement crosswise of the axis and adapted to be assembledand separated by a movement longitudinal of the axis, bails spanning the ends of the assembled spider, and bolts inserted through the ends of the bails and'through the spider. 6. 'A split spider comprising a lower partandian upper partythere being a half bear ring block on the lower part and a half bearblocks, and there being vertical. pillars extending outwardly from the ends of the. first bearing block above the lower supporting blocks and there being flanges extending np wardly from the lower supporting blocks, and there being vertical recesses in the upper supporting blocks to receive the vertical pillars and there being recesses in the upper supporting blocks to receive the vertical flanges, so that the upper part will match with the lower part upon a downward movement of theuppe-r part to a level with the lower part, and so that the upper part cannot pass downwardly below the lower part, and so that the two parts cannot separate on alinecrosswise of the-axis of the vertical opening.

In testimony whereof we have signed our names to this specification.
